java加载并运行虚拟机_《深入理解Java虚拟机》- Java虚拟机是如何加载Java类的?...
Java虛擬機是如何加載Java類的？? 這個問題也就是面試常問到的Java類加載機制。在年初面試百戰之后，菜鳥喜鵲也是能把這流程倒背如流啊！但是，也只是字面上的背誦，根本就是像上學時背書考試一樣。
tonight ！ 我們把它映射到實戰里，看看如何用代碼說明這個流程。
ready! go!? ----------------在這之前還是搞點理論吧，不然又要先去百度加載機制流程了。
一、類加載機制(理論部分)
類加載機制有三大過程：加載、鏈接、初始化。其中鏈接又細分為驗證、準備及解析。
Java語言的類型分為兩大類：基本類型和引用類型。Java的基本類型是由Java虛擬機預先定義好的。而引用類型又分為：數組類、類、接口、泛型參數。在JVM中，只存在數組類、類、接口三類，而數組類是直接由Java虛擬機直接生成的，其他兩類則有字節流而來。
字節流又是怎么來呢？最常見的還是從字節碼文件而來(還可以從網絡等而來)。所以，我就以字節碼文件分析一下加載機制。
1.加載
加載是指查找字節流，并據此創建類的過程。對于數組類來說，它們是可以由Java虛擬機直接生成。而其他兩類，卻需要借助類加載器，Java虛擬機才能完成查找字節流的工作。
類加載器與類的關系就像是UI與效果圖一樣，需要將業務需求翻譯成效果圖。美麗的UI就是類加載器，效果圖就是類。
類加載器有一個模型：雙親委派。
雙親委派模型是每次收到類加載請求時，先將請求委派給父類加載器完成，如果父類加載器無法完成加載，那么子類嘗試自己加載
類加載器分為三種，啟動類加載器、擴展類加載器、應用類加載器。
其中，
啟動類加載器(Application ClassLoader)是負責加載最為基礎、最為重要的類，即加載\lib目錄下核心庫
擴展類加載器的父類加載器是啟動類加載器，擴展類加載器負責加載相對次要、但又通用的類，即加載\lib\ext目錄下擴展包
應用類加載器的父類加載器是擴展類加載器，應用類加載器負責加載應用程序路徑下的類，即用戶路徑(classpath)上指定的類庫
這三者類加載器的關系可以這樣描述：
每當類加載器接收到加載請求時，它會先將請求轉發給父類加載器，在父類加載器中沒有找到需要的類的情況下，該加載器才會嘗試去加載。
比如，應用加載器接收到加載請求，會先去找父類加載器(擴展類加載器)里有沒有需要的類，但該擴展類加載器頂頭還有父類加載器(啟動類加載器)，所以還要去啟動類加載器中查找是否存在需要的類，如果不存在，那擴展類加載器就會自己加載需要的類，然后把引用傳遞給應用加載器。
類加載器還有一個功能，就是提供命名空間的作用。
在Java虛擬機中，類的唯一性是由類加載器實例以及類的全名一同確定的。即便是同一串字節流，經過不同的類加載器加載，也會得到兩個不同的類。(這里可以讀者自己實現一下，用兩個擴展類加載器加載同一個類，然后打印一下類信息就可以驗證了)
2.鏈接
鏈接：將創建成的類合并至Java虛擬機中，使之能夠執行的過程。(這里是下面代碼要驗證一個步驟)
鏈接分為驗證、準備、解析。
驗證的目的是為了讓被加載的類能夠滿足Java虛擬機的約束。(關于約束條件，今天暫時不講。)
準備的目的是為了被加載類的靜態字段分配內存。(僅僅是分配內存，并沒有在內存中寫東西)除此之外，有些Java虛擬機還會用來實現虛方法的動態綁定的方法表。
下一步就是我們鏈接的重要步驟--解析
對于一個方法的調用，編譯器會解析一個符號，這個符號能夠無歧義地定位到具體的目標上。這個符號包含目標方法所在類的名字、目標方法的名字、接收的參數類型以及返回值類型的符號引用。
如果符號引用指向一個未被加載的類、字段、方法，那么這個解析將觸發加載功能。
3.初始化
初始化：為標記為常量值的字段賦值，以及執行方法的過程。
只有初始化完成之后，類才正式成為可執行的狀態。
那初始化這個步驟是什么時候執行呢？
JVM規范枚舉了下述多種觸發初始化的情況：
理論部分講解完了。(參考鏈接：https://time.geekbang.org/column/article/11523)
二、類加載機制(Linux查看字節碼)
在這，主要是因為網上都是一大串的理論描述，看得也是半信半疑。還不如拿出代碼來，讓自己也心服口服了。
talk is cheap,show the code!
1.classloader
輸出如下：
結果很驚人，為什么父類加載器的父類加載器(我自己取名為爺爺類加載器。。)，照理論來說，應該打印的是bootstrapClassLoader。 其實是它隱身了。貼一下代碼里的一段注釋：
* Returns the parent class loader for delegation. Some implementations may
* use null to represent the bootstrap class loader. This method
* will return null in such implementations if this class loader's
* parent is the bootstrap class loader.
翻譯黃色的句子就是：如果父類加載器是啟動類加載器，則將返回null
但還是沒解決怎么找bootstrapClassLoader啊。
它實際上不是 java.lang.ClassLoader的子類，而是由JVM自身實現的，我們可以通過這個方法得到實現的類路徑。
URL[] urls=sun.misc.Launcher.getBootstrapClassPath().getURLs();
2.鏈接
3.初始化
1.編譯的單例類：Singleton.java
public classSingleton{privateSingleton(){}private static classLazyHolder{static final Singleton INSTANCE = newSingleton();static{
System.out.println("LazyHolder.");
}
}public static Object getInstance(booleanflag){if(flag) return new LazyHolder[2];returnLazyHolder.INSTANCE;
}public static voidmain(String... args){
System.out.println("---");
getInstance(true);
System.out.println("---");
getInstance(false);
}
}
2.編譯并運行
[root@localhost tmp3]# javac Singleton.java
[root@localhost tmp3]# java Singleton---
---LazyHolder.
3.查看字節碼文件(用的新指令：java -verbose:class Singleton)
結合2,3的輸出，我想，我該講點啥。
在兩段“-----”中，如果沒有打印加載信息，我們就以為是連續輸出了。但是并沒有。根據加載信息來看，中間還會加載Singleton$LazyHolder這個內部類，而這一步，對應的就是getInstance(true)；。說明了啥？說明了前面理論部分的鏈接的最后一句話：
如果符號引用指向一個未被加載的類、字段、方法，那么這個解析將觸發加載功能。
這里注意的是，僅僅調用了加載功能而已，這里只完成了創建類而已，并沒有讓它繼續進行鏈接和初始化功能。所以在這里，也就不會出現打印“LazyHolder.”的字樣。
當使用到了getInstance(true)的時候，由于需要使用到“LazyHolder.INSTANCE;”這個靜態常量，而它又與new 構造器方法相連通，此時就滿足了理論中初始化的解釋：
2.當遇到用以新建目標類實例的new指令時，初始化new指令的目標類
3.當遇到訪問靜態字段的指令時，初始化該靜態字段所在的類
在這，大家應該也有疑問：getInstance(false)的時候也有new啊。但是，false時候的new，只是new數組，數組里裝的只是加載時候生成的類引用。
大家還可以看下面class字節碼就知道，注釋那里就標記著很清楚是類引用而已。
Singleton.class

flags: ACC_SYNTHETIC
Code:
stack=1, locals=2, args_size=2
0: aload_01: invokespecial #1 //Method "":()V
4: returnLineNumberTable:
line1: 0}
可以看到，在getInstance中，那么#3 和#4 對應的是啥
現在，
看了例子之后，大家應該也對類加載機制有了一點點了解了吧。
